Autosampler

Abstract

A needle driver moves a sampling needle. A display controller displays a layout input portion for receiving input of layout information in regard to an additional sample container in a display unit. A position information acquirer acquires position information representing positions of a predetermined count of containing portions in an additional sample container based on teaching work. A storage stores the input layout information and the acquired position information. A designation information acquirer acquires designation information designating a containing portion. A movement controller controls the needle driver based on the stored layout information, the stored position information and the acquired designation information such that the sampling needle is moved to the containing portion designated by the designation information.

1 . An autosampler that collects a sample from each containing portion of a sample container, comprising:
 a holder that can selectively hold a default sample container and an additional sample container different from the default sample container;   a sampling needle;   a needle driver that moves the sampling needle;   a layout input portion that receives input of layout information including a layout and a count of a plurality of containing portions in the additional sample container in accordance with a defined input format displayed in a layout information input screen in which a layout input field for input of a hole count is provided;   a position information acquirer that acquires position information representing positions of a predetermined count of containing portions in an additional container held by the holder based on teaching work;   a storage that stores layout information input to the layout input portion and position information acquired by the position information acquirer;   a designation information acquirer that acquires designation information designating a containing portion to which the sampling needle is to be moved out of the plurality of containing portions in an additional sample container held by the holder; and   a movement controller the controls the needle driver based on the stored layout information, the stored position information and the acquired designation information such that the sampling needle is moved to a containing portion designated by the designation information.   
     
     
         2 . The autosampler according to  claim 1 , wherein
 the plurality of containing portions in the additional sample container are arranged in first and second directions that intersect with each other, and   the layout information includes a count of containing portions arranged in the first direction and a count of containing portions arranged in the second direction.   
     
     
         3 . The autosampler according to  claim 2 , wherein
 the plurality of containing portions in the additional sample container are arranged to constitute a plurality of first lines in parallel with the first direction and a plurality of second lines in parallel with the second direction, and   the autosampler further includes a deviation amount acquirer that acquires at least one deviation amount of a deviation amount in the first direction between containing portions corresponding to each other in two adjacent second lines and a deviation amount in the second direction between containing portions corresponding to each other in two adjacent second lines, in a case in which containing portions corresponding to each other in two adjacent second lines of the additional sample container are deviated from each other by a certain amount in the first direction,   the storage stores a deviation amount acquired by the deviation amount acquirer, and   the movement controller controls the needle driver such that the sampling needle is moved to a containing portion designated by the designation information based on the stored layout information, the stored position information, the acquired designation information and the stored deviation amount.   
     
     
         4 . The autosampler according to  claim 3 , further comprising a display controller that displays contents of the layout input portion in a display unit,
 the display controller displays a deviation amount input portion for receiving input of the at least one deviation amount in the display unit, and   the deviation amount acquirer acquires a deviation amount input to the deviation amount input portion.   
     
     
         5 . The autosampler according to  claim 3 , further comprising a deviation amount calculator that calculates the at least one deviation amount based on the stored position information, wherein
 the deviation amount acquirer acquires a deviation amount calculated by the deviation amount calculator.   
     
     
         6 . The autosampler according to  claim 1 , further comprising a display controller that displays contents of the layout input portion in a display unit, wherein
 the display controller displays a selector for selecting which one of the default sample container and the additional sample container is to be held by the holder in the display unit, and displays the layout input portion in the display unit in a case in which the additional sample container is selected by the selector.
